BURNER FDR VAPOR-LAMPS.

To all whom it may concern:

Be it known that I, GEORGE WV. RANDALL, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Burners of Lamps for Generating and Burning Hydrocarbon Vapor; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which Figure 1, is an external view, and Fig. 2, a vertical section of a burner containing my invention; Fig. 3, is a side view of the valve as separated from the generator and the button or heat absorber. Fig. 4:, is a view of the spring, while Fi 5, is a section taken through the discharging orifices of the valve and the vapor generator.

The nature of my invention consists in an improvement in the application of a valve and its seat to the vapor generator and the heat absorbing button or disk.

In the drawings, A, denotes the vapor generator, screwed on the upper end of a tube, D, which may be supposed to represent the wick tube of a hydrocarbon vapor lamp. This generator is made tapering at top or formed with a conical valve, 7), in the upper part of it and so as to receive a tapering or conical valve, B, whose shank or neck, (Z, extends through the upper part of the generator, and screws into a button, C, as shown in Fi 2, the button beingmade entirely separate rom the valve. Surrounding the shank or neck, (Z, of the valve, B, is a helical spring, E, which is shown in Figs. 2, and l, and rests on the top of the generator, A, and within a cup shaped recess, a, formed therein to receive it. The heat absorbing button, C, screws down upon the spring in a manner to connect the same and thereby cause the valve to be drawn closely up to its seat.

Both the valve and the generator are furnished with a series of discharging orifices or jet holes, as seen at a, a, in the drawings, they being arranged in the two in such manner as to enable a person by turning the valve around by means of power applied to the button, O, to close either one or more or all of the orifices, a, a, a, a, as circumstances may require. WVhen the burner is in use, the heat of the inflamed jets of va- Specification of Letters Patent No. 21,053, dated July 27, 1858.

por issuing from the holes, a, a, will be more or less absorbed by the button, C, and by it will be conducted into the valve and spring from whence it will flow into the generator so as to vaporize the liquid taken up in the wick by capillary attraction.

I lay no claim to a tube or annulus having et holes through it and so encompassing a vapor generator, and the series of discharging orifices of a hydro-carbon vapor lamp as to operate as a valve or cover to such orifices and enable a person to cut off the passage of combustible vapor out of any one or more of them while the lamp may be in use. Nor do I claim the combination of a hollow spur having a series of discharging apert-ures with a vapor generator furnished with a similar series of apertures, as no spur to enter the wick is essential to my invention, and besides a spur screwed into the vapor generator and having the orifices of ejection formed in it is highly objectionable, as the vapor is liable to leak between the helix threads of the spur and those of the corresponding sorew of the generator. Furthermore, the great heat which the spur conducts into the wick often causes the latter to become charred or burned, especially when the wick is surrounded by a heated tube or generator. In making my improvement I have sought to avoid all such objections, and at the same timeplace the valve or register within the body of the generator instead of arranging it 011 the outside thereof.

\Vhat I claim is My improvement in the application of the valve and its seat to the generator and the button or heat absorber, the same consisting in makin such valve and seat tapering, and arranging them in the generator, and maintaining them in contact by the action of a spring, and connecting the valve with a separate button in such manner, that the button besides performing its oflice of absorbing heat from the flame, may serve with the spring to maintain the valve in place against its seat and to rotate the valve as specified.

In testimony whereof I have hereunto set my signature.

GEORGE WV. RANDALL.
